Unplug the main power cable before opening the housing.
| Interval | Task | |----------|------| | Monthly | Clean condenser filter, inspect rotor for corrosion. | | Quarterly | Check lid seal integrity, measure imbalance threshold. | | Annually | Calibrate temperature display (±1°C), test emergency lid release, replace drive belt (if applicable). |
Understanding the technical baseline is the first step in any service or maintenance procedure. 15,000 rpm (21,130 x g). Capacity: 24 x 1.5/2.0 mL tubes.
Regularly inspect the rubber O-rings embedded in the rotor lid. If the O-ring is brittle, cracked, or flattened, it must be replaced immediately to maintain biosafety integrity. The service manual outlines procedures to: While the
Use a calibrated external probe to confirm the rotor chamber temperature at 4°C. Check Time: Ensure the timer accuracy. 6. Accessing the Service Manual and Technical Support
: Use pH-neutral detergents on the chamber, rotor, and adapters.
Always use appropriate decontamination procedures (e.g., 70% ethanol) before service.
